Description

Convertible dual purposes of sitting and lying folding seat

Technical field:

The utility model belongs to small stores field, particularly a kind of convertible dual purposes of sitting and lying folding seat.

Background technology:

existing dual purposes of sitting and lying folding seat, especially adopt folding support rod member and flexible cushion fabric combination folding chair, as the patent No., mostly consider from the angle of regulating back gradient, patent No. CN20162356U how, the disclosed seat folding seat of lying, its structure includes backrest, seat, arm-rest frame, leg support and foot support, the bottom of backrest and the rear end of seat are hinged, the front end of seat and the middle and upper part of leg support are hinged, the rear end of arm-rest frame and backrest middle and lower part are hinged, the front end of arm-rest frame and the upper end of leg support are hinged, foot support divides front U-shaped bar and rear U-shaped bar, the top of the top of front U-shaped bar and rear U-shaped bar is hinged to one, the arm-rest frame below is provided with sliding locking mechanism, the top of sliding locking mechanism and foot support is hinged, be connected with the L shaped connecting rod that strides across rear U-shaped frame between seat and front U-shaped frame, the minor face of L shaped connecting rod is shelved on rear U-shaped frame.This provides a kind of form of dual purposes of sitting and lying folding seat, but structure is comparatively complicated.How to create the structure of new-type dual purposes of sitting and lying folding seat, namely become the object of the utility model research.

Summary of the invention:

The purpose of this utility model is a kind of rod member that passes through two mutual cross-articulation of design, bending have two the location, by different the locations of overturning, the convertible dual purposes of sitting and lying folding seat of selecting or sitting or lie.

Technical solutions of the utility model are achieved in that a kind of convertible dual purposes of sitting and lying folding seat, comprise supporting rod and cushion fabric, it is characterized in that supporting rod includes two mutual cross-articulation rod member together and related rod member; The middle part bending of two rod members of counter structure, the both sides of bending form respectively first the location and second the location, described first the location and second the end, location inwardly be bent with again first fold curved segment and the second bending section, rod member is bent into the enclosed structure; First the location than second segment length that lands, described two rod member cross-articulation points be in first on the location, at least second be provided with folding related rod member between two rod members of location one side; Four jiaos of described cushion fabrics are suspended on the end of first fold curved segment and the second bending section.

Described related rod member is two U-shaped bars, U-shaped bar two ends be hinged on same rod spare second on location and the second bending section, the two nearly U-shapeds of U-shaped bar bottoms mutually cross-articulation together, and two U-shaped bars can be around pin joint toward inboard folding.

Described two U-shaped bars are small one and large one structure, and it is inboard that little U-shaped rod member part can be enclosed within large U-shaped bar; The bottom curvedly goes out toward interior large U-shaped bar from pin joint to U-shaped, and this curved side-play amount that goes out is greater than the diameter of little U-shaped bar, and two U-shaped bars can form interference and open.

Described related rod member is the straight rod member of two interference fit, straight rod member one end be hinged on second on the location, the other end is hinged.

The utility model is skillfully constructed, the characteristics of reasonable in design, simple for structure, exotic shape; The seat conversion of lying only needs an angle of turn-over folding chair to land and gets final product, globality and good stability; In addition, four jiaos of cushion fabrics are suspended on Rod end, similar hammock effect, and by the strain of rod member, sit lie more high resilience, very Leisure.

The specific embodiment:

With reference to Fig. 1, Fig. 2 and Fig. 3, convertible dual purposes of sitting and lying folding seat comprises supporting rod and cushion fabric 1, and supporting rod includes two mutual cross-articulation rod member 2 together and related rod member 3; 2 one-tenth counter structures of two rod members, it can be specifically same structure, perhaps symmetrical structure, the middle part bending of described two rod members 2, the both sides of bending form respectively first location 21 and second location 22, and first location 21 and second 22 ends, location inwardly be bent with again first fold curved segment 23 and the second bending section 24, make rod member 2 be bent into the enclosed structure, supporting mat fabric 1 is unlikely to fabric to be encountered on rod member; First location 21 to the second location 22 long, two rod member 2 cross-articulation points 4 be in first on location 21, and second 2 of two rod members of location 22 1 sides be provided with folding related rod member 3; Related rod member 3 can adopt following two kinds of structures, one, as shown in the figure, related rod member 3 is two U-shaped bars 31, U-shaped bar 31 two ends be hinged on same rod spare second on location 22 and the second bending section 24, say exactly and be hinged with Connection Block 5 on rod member 2, U-shaped bar 31 ends are hinged on this Connection Block 5, support and folding angle in order to regulate; The two nearly U-shapeds of U-shaped bar 31 bottoms 32 mutual cross-articulation together, and two U-shaped bars can be around the past inboard folding of pin joint 4.Described two U-shaped bars 31 are small one and large one structure, and it is inboard that little U-shaped rod member part can be enclosed within large U-shaped bar; Bottom 32 curvedly goes out toward interior large U-shaped bar from pin joint 4 to U-shaped, and this curved side-play amount that goes out is greater than the diameter of little U-shaped bar, and two U-shaped bars can form interference and open; Above-mentioned U-shaped bottom curvedly goes out toward interior, and this refers to the inboard toward rod member 2 enclosed structures toward in, should the past interior receipts of association rod member 3 when folding, do not account for space outerpace.

Two, related rod member 3 also can be the straight rod member of two interference fit, straight rod member one end be hinged on second on location 22, the other end is hinged.Also be about to above-mentioned U-shaped bar and be simplified to a straight rod member, can reach equally the purpose that two rod members 2 are strutted, structure is more succinct.

With reference to Fig. 4 and Fig. 5,1 four jiaos of cushion fabrics are suspended on the end of first fold curved segment 23 and the second bending section 24, and 1 one-tenth hanging shape of cushion fabric is sat, during recumbency, can be wrapped in the health outside, and are naturally comfortable; And the conversion of sitting, lying, only need upset one angle is got final product, as the sitting posture of Fig. 4, shorter second location 22 land, form less cushion position and higher backrest, meet the sitting posture requirement; When thinking recumbency, toward backrest one lateral overturning, allow the backrest face land, also namely allow long first location 21 land, have long cushion and shorter backrest, satisfy and lie by the posture requirement, namely as the formula of the lying state of Fig. 5.When actual folding seat is made, first location 21 to the second on location 22, also be arranged with foot pad, both be used for regulating the injustice of crossing rod piece, can reduce again the direct kiss the earth of rod member, also shield.

Folding seat is the used time not, only needs related rod member 3 with interference fit toward interior pressure, walks around interference section, two rod members 2 can be closed up folding, saves the collection parking space, and what be fit to very much garden leisure need.
