Abstract

The utility model discloses a fold-away bed mainly including two long struts, a plurality of X shape cross braces are provided under the two long struts, a strut is connected between the long struts and the cross braces. The strut pulls or pushes the cross braces at two sides when folding or unfolding the strut, making the cross braces fold or unfold automatically thereby saving a step and making the operation more convenient and labor-saving comparing to current technique.

Description

Folding bedstead

Technical field

The utility model relates to a kind of household goods, refers to a kind of folding bedstead especially.

Background technology

At present the kind of folding bed is of all kinds, because its folding volume is little, is convenient to collection and carries, and therefore is not only applicable to use at home, and is more suitable in amusement and travel, outdoor sports.Common a kind of folding bed structure is as Granted publication on July 21st, 1999, and Granted publication number is the Chinese utility model patent of CN2329247Y, and name is called " a kind of folding bed ".This folding bed mainly comprises two long fulcrum bars and some in order to support " X " shape cross brace of two long fulcrum bars, then is fixed with a cloth on two long fulcrum bars.This folding bed is upwards mentioned the both sides long fulcrum bar earlier and is inwardly drawn in when folding, the both sides cross brace is inwardly revolved 270 degree and draw close with two long fulcrum bars of turning 90 degrees or outwards overturn again, and so promptly finishes the folding process.If long fulcrum bar is oversize, it can be formed by connecting by two connecting rods, at this moment, again with two connecting rod doublings up or down of long fulcrum bar, stops up then during folding, and the volume after its folding is littler, is easy to carry.

Yet above-mentioned folding bed must be divided into several steps when folding, promptly after the both sides long fulcrum bar being mentioned and inwardly draw over to one's side, also need artificially long fulcrum bar to be drawn close in cross brace rotation in both sides, and then the doubling long fulcrum bar, also want anti-phase repetition above-mentioned steps during expansion, therefore use comparatively trouble.

The utility model content

The purpose of this utility model is to provide a kind of folding and expansion to be more prone to and folding easily bedstead.

For achieving the above object, technical solution of the present utility model is:

A kind of folding bedstead, it mainly comprises two long fulcrum bars, in the supported underneath of two long fulcrum bars some " X " shape cross brace is arranged, and is connected with a pole between the cross brace at described long fulcrum bar and two ends.

Described long fulcrum bar is formed by connecting by two connecting rods.

The central supported underneath of described long fulcrum bar has one group of cross brace.

The central authorities of described long fulcrum bar, promptly the junction of two connecting rods is supported with two groups of cross braces side by side, and is provided with the fixed structure that both can be fixed on these two groups of cross braces.

After adopting such scheme, because the utility model is provided with a pole between the cross brace at two long fulcrum bars of folding bedstead and two ends, this pole is in folding bed folding and expansion process, can spur or promote the cross brace at two ends, make its folding automatically or expansion, therefore compare prior art, saved a step, thereby made more convenient to operate, laborsaving.

The specific embodiment

As shown in Figure 1, folding bedstead described in the utility model mainly comprises two long fulcrum bars 1, in the supported underneath of two long fulcrum bars 1 some " X " shape cross brace 2 is arranged.Wherein:

This long fulcrum bar 1 is formed by connecting by two connecting rods 11, then respectively supports one group of cross brace 2 in the two ends and the central authorities of long fulcrum bar 1.Support steadiness for increasing, in long fulcrum bar 1 central authorities, promptly the junction of two connecting rods 11 can be supported two groups of cross braces 2 side by side, can when folding bed launches both be fixed side by side and be provided with fixed structure 3 on these two groups of cross braces 2.

Difference of the present utility model is: be connected with a pole 4 between the cross brace 2 at long fulcrum bar 1 and two ends.This pole 4 can make cross brace 2 supports at two ends more firm when folding bed launches, and in addition, this pole 4 also can be played the effect of auxiliary two ends cross brace 2 foldings or expansion.Specifically describe as follows:

,, earlier long fulcrum bar 1 is upwards mentioned and inwardly gathering when the utility model is desired folding to shown in Figure 5 as Fig. 2, at this moment, under the pulling of described pole 4, the inwardly rotation automatically of the cross brace 2 at two ends is until drawing close fully with long fulcrum bar 1; Then, fixed structure between the two groups of cross braces 2 in middle part 3 is removed, these two groups of cross braces 2 are broken away from, again with two groups of cross braces 2 respectively to two sideway swivels, up to long fulcrum bar 1 parallel longitudinal, last again with two connecting rods, the 11 upwards doublings of long fulcrum bar 1, so promptly finish the folding process.Certainly, the cross brace 2 at two ends is being drawn close under the pulling of pole 4 automatically behind long fulcrum bar 1, also can be with two connecting rods, the 11 downward doublings of long fulcrum bar 1, thus in the middle of two groups of cross braces 2 at middle part were sandwiched in, it can reach the purpose of folding equally.And described folding bed desire only need be carried out anti-phase action when launching, and after two connecting rods 11 of long fulcrum bar 1 were flattened, only need outwards draw back both sides long fulcrum bar 1, and the cross brace 2 at folding bed two ends promptly can be propped under the promotion of pole 4 automatically.From above-mentioned analysis as can be known, described pole 4 can spur or promote the cross brace 2 at two ends in folding bed folding and expansion process, make its folding automatically or expansion, therefore makes more convenient to operate, laborsaving.

Claims

1, a kind of folding bedstead, it mainly comprises two long fulcrum bars, in the supported underneath of two long fulcrum bars some " X " shape cross brace is arranged, and it is characterized in that: be connected with a pole between the cross brace at described long fulcrum bar and two ends.

2, folding bedstead as claimed in claim 1 is characterized in that: described long fulcrum bar is formed by connecting by two connecting rods.
