Description

Futon sofa bed

Technical field

The utility model relates to a kind of furniture, refers to a kind of Futon sofa bed especially.

Background technology

Futon (futon) divan is a kind of common composite furniture, and it is owing to be easy to carry out mutual conversion in positions such as sofa and divans, uses and does not take up space, and therefore market widely arranged.And this Futon sofa bed when dispatching from the factory, be to pack with the form of parts, assembling voluntarily again after the consumer buys back.In the prior art, this is Futon sofa bed is generally disassembled into following several parts: two arm-rest frames, a back rest, a cushion frame, some beams and some other necessary connectors etc.Yet but there is following deficiency in this mode of disassembling:

1. because the length of back rest and cushion frame is longer usually, generally be equivalent to the length of bed, therefore cause the length of packing oversize, thereby be unfavorable for carrying, also increased cost of transportation.

2. because the length specification of this divan has a variety ofly, like this for producer, just must prepare the back rest and the cushion frame of all lengths specification, thereby be unfavorable for normalization, and then increase manufacturing cost.

For this reason, this case the designer expect, even each is different for described Futon sofa bed length specification, but the length and width size of its arm-rest frame is the same usually, if therefore can make the size of the size of other each parts and arm-rest frame suitable, then can significantly reduce Package size.

The utility model content

The purpose of this utility model is to provide a kind of the Futon sofa bed of Package size that significantly reduce.

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

A kind of Futon sofa bed, comprise two arm-rest frames, a cushion frame, a back rest, some bed beams and be connected in the two angular adjustment assemblies at this cushion frame and back rest two ends; Described cushion frame and back rest by two limit racks after interconnecting and at least one rack constitute; Described bed roof beam structure is located between two arm-rest frames, and every bed beam is formed by at least two short unit bars, and the bottom connects the middle part leg is arranged between two adjacent unit bars.

Be connected with rack in one or two between two limit racks of described cushion frame and back rest.

The length and width size of described limit rack and middle rack and described arm-rest frame quite.

Be connected by a connecting piece between described limit rack and the middle rack.

Be connected by a coupling hook between cushion frame after the described assembling and the back rest.

After adopting such scheme,, can reduce packing cost because the utility model cushion frame that length is long and back rest resolves into attachable two limit racks and rack at least one can significantly reduce the Package size of product like this, and the carrying of being more convenient for.In addition, the utility model can make the limit rack and in rack length and width size and described arm-rest frame quite, so no matter be the divan of which kind of length specification, the length and width size of its packing case is that thickness is different all equally.Moreover the quantity of rack during the utility model only need be adjusted can conveniently change the length of divan, and the limit grid structure at each angle too, therefore can make product reach normalization, greatly reduces manufacturing cost.

The specific embodiment

As shown in Figure 1, Futon sofa bed two arm-rest frames 1, four limit racks 2, at least two middle racks 3, some bed beams 4, some middle parts leg 5, two angular adjustment assemblies 6 and some connectors of mainly comprising described in the utility model.Wherein:

The structure of described arm-rest frame 1 is same as the prior art, and it is a plate body.

The length and width size of described limit rack 2 and middle rack 3 and above-mentioned arm-rest frame 1 quite, and two limit racks 2 are connected afterwards a cushion frame A of formation or a back rest B with rack 3 at least one.

Described bed beam 4 is set up between two arm-rest frames 1, and every bed beam 4 is formed by at least two short unit bars 41.

Described middle part leg 5 can be arranged between above-mentioned two adjacent unit bars 41, and it is in order to connection and support two unit bars 41.

Described angular adjustment connector 6 one ends are connected on the end and arm-rest frame 1 of described cushion frame A, and the other end then is connected in the end of described back rest B, and its structure is common connection and angle adjustment mechanism, does not give unnecessary details at this.

Described connector is in order to auxiliary described limit rack 2 and the middle rack 3 of connecting, or between described cushion frame A and the back rest B, it can be brace 71 and is used for connecting this limit rack 2 and rack 3, also can be coupling hook 72 and is used to connect this cushion frame A and back rest B.

The utility model is in when assembling, as shown in Figure 2, the outer end of described unit bar 41 is connected on the both sides arm-rest frame 1, simultaneously again with 5 of described middle part legs in and be connected between the two adjacent unit bars 41, thereby unit bar 41 is connected into a beam 4; And then with two limit racks 2 and a middle rack 3 be formed by connecting a cushion frame A and a back rest B; Again two cushion frame A that assemble and back rest B are connected in both two ends with described angular adjustment connector 6 afterwards; Be connected to corresponding position with described brace 71 and coupling hook 72 again; Last again cushion frame A and the back rest B that fits together is positioned on the above-mentioned bed beam 4, and simultaneously an end of angular adjustment connector 6 is connected on the arm-rest frame 1, thereby finish assembling.
