Description

A kind of durable divan

Technical field

This utility model relates to field of furniture, particularly to a kind of PU surface, the divan of inner sponge cores.

Background technology

At present, in the Decoration for Living Room of average family, often use sofa group, especially in the case of bulk allows, it will usually coordinate sofa group that one divan is set in the position near window limit.It is different from common sofa group, owing to divan is typically to be used for lying low or half chair, thus divan is higher generally for the requirement of pliability, thus, its structure is typically: use the soft foam-rubber cushion of monoblock as liner, the materials such as PU, corium or cloth are as infantees, by wooden frame or the structure of steel skeletal support of rigidity, by the skeleton support for foam-rubber cushion, the sofa face being wrapped to form a soft comfortable of infantees.And in use for some time; flexible foam-rubber cushion can be difficult to due to long-term pressurized recover to original shape; for common sofa group; foam-rubber cushion is supported by the elastic component that would generally arrange some elastic stiffnesss bigger inside it; and coordinate the sponge selecting some quality the hardest as cushion, so prevent the deformation in sofa face.

But, for divan, whole body wt can be all supported on the foam-rubber cushion on divan by user, so, divan there will be in use for some time large-area foam-rubber cushion cannot the phenomenon of resilience, sofa group can be shorter than its service life, but, foam-rubber cushion on existing divan is monoblock, the most locally occur cannot the deformation of resilience, need monoblock to change foam-rubber cushion the most whole sofa group.

Utility model content

The purpose of this utility model is to provide a kind of durable divan, and foam-rubber cushion thereon can carry out the replacing of local, to promote the durability of divan itself.

Above-mentioned purpose of the present utility model has the technical scheme that a kind of durable divan, include the support frame of divan, some blocks of separate foam-rubber cushions it are provided with on described support frame, the connecting plate for fixing both it is provided with between described support frame and foam-rubber cushion, described connecting plate is detachably fixed with support frame and is connected, described some blocks of foam-rubber cushions are spliced into the sofa face of a monoblock, and described sofa face outsourcing is provided with surrounding layer.

Further, described connecting plate includes and forms the frame on its four limit and be arranged at the divider between described frame, and the Line Integral surrounded between described frame is divided into some subregions by described divider.

Further, it is provided with connector between the divider that described any two intersects.

Further, it is provided with the elastic network(s) for bear external force between described frame.

Further, described foam-rubber cushion is divided into elastic group of equivalent according to the number of described subregion.

Further, four angles of described connecting plate being provided with the gusset for supporting the foam-rubber cushion at square position, described gusset is fixed on described connecting plate.

Further, it is adhesively fixed between bottom and the described connecting plate of described foam-rubber cushion.

Further, described surrounding layer includes crust and elastic lining cloth, and described elastic lining cloth is directly wrapped in outside all foam-rubber cushions, and described outer suitcase is located at outside described elastic lining cloth.

In sum, this utility model has the advantages that the form that the foam-rubber cushion of divan is made some blocks of separate foam-rubber cushions, and by connecting plate and surrounding layer, some blocks of foam-rubber cushions are fixed on support frame, and form the sofa face of a monoblock, so, when a certain local location on sofa face subsides, can be directly to be replied the flatness in sofa face by the form changing the foam-rubber cushion of corresponding and adjacent area, and without carrying out the replacing of entirety, to improve the durability of sofa.Further, owing between connecting plate and support frame being detachable fixing annexation, thus, this process changing local foam-rubber cushion is also the most easily operated.

Detailed description of the invention

Below in conjunction with accompanying drawing, this utility model is described in further detail.

A kind of durable divan, as shown in fig. 1, includes the elastic sofa face being supported in ground support frame 1 and being laid on support frame 1, also sets up resilient backrest 6 and handrail 5 on support frame 1, and both of which is fixed on support frame 1.

Specifically, if Fig. 2 is to as shown in 3, sofa face is spliced to form by some separate foam-rubber cushions 2, outside bag at foam-rubber cushion 2 is provided with surrounding layer 4, and preferably surrounding layer 4 includes crust 41 and elastic lining cloth 42, wherein, foam-rubber cushion 2 is coated with the shape in end face evagination by elastic lining cloth 42, crust 41 uses PU or corium uniform wearability material to make, it is outside that crust 41 is coated on elastic lining cloth 42, the benefit so arranged is, crust 41 only serves the effect that cladding is wear-resisting, the increase of elastic lining cloth 42 too increases the frictional force between crust 41 and foam-rubber cushion 2, prevent long-term pressurized crust sliding or fold.

Further, if Fig. 4 is to as shown in 5, between foam-rubber cushion 2 with support frame 1, the connecting plate 3 being connected the relativeness fixing both it is provided with.Connecting plate 3 includes four edges frame 31, some dividers 32, connector 33 and elastic network(s) 34, wherein: frame 31 finishes up sequentially to connect and forms a rectangular frame, the ending of each frame 31 is provided with 45 degree of inclined-planes, the mutual split in inclined-plane of two frames 31 connected forms a right angle, this right angle is provided with gusset 35, gusset 35 here functions as two effects: one is the position relationship of fixing adjacent two frames 31, two is that the foam-rubber cushion 2 giving this position is to support, experience is used according to Yin, corner for instruct volume foam-rubber cushion 2 be easiest to occur breakage, increase gusset 35 to play a supporting role to the foam-rubber cushion 2 in corner.Divider 32 is the most arranged in a crossed manner inside rectangular frame, interior zone is divided into some subregions, if foam-rubber cushion 2 is correspondingly also classified into dry elasticity group, the intersection of divider 32 is pointed out and is provided with connector 33, connector 33 is the rectangular metal sheet in a hole being provided with 5, five anchor points limit the relative position relation between divider 32 or between divider 32 and frame 31, and this fixed form can be formed the most fixing between each framework.

As preferably, open in the rectangular frame of frame 31 composition and be provided with elastic network(s) 34, elastic network(s) 34 can be by the single setting of the number of words of subregion, can also whole be arranged in rectangular frame, when foam-rubber cushion 2 is installed to connecting plate 3, can be bonded to simultaneously frame 31 or divider 32 with on elastic network(s) 34, each equal front of foam-rubber cushion 2 is made to bond, further, elastic network(s) 34 can also give foam-rubber cushion 2 supporting role in actual use, extends its service life.

In use, when elastic group in certain sub regions subsides, can directly take the annexation of support frame 1 and connecting plate 3 apart, and the foam-rubber cushion 2 of corresponding region is removed, and frame 31 and divider 32 are cleared up, and the new foam-rubber cushion 2 of the correspondingly-sized that bonds at this, so, sofa machine tool occur local collapse time need not whole Zhang Genghuan spongy layer, can be replaced with subregion, extend the service life of divan.

This specific embodiment is only to explanation of the present utility model; it is not to restriction of the present utility model; the present embodiment can be made after reading this specification by those skilled in the art as required does not has the amendment of creative contribution, but as long as all being protected by Patent Law in right of the present utility model.
