Abstract
Disclosed is a back cushion, which comprises a back cushion core and a back cushion cover, wherein the back cushion cover wraps around the back cushion core, and the back cushion core comprises a back cushion core cover and packing fillings which are filled in the back cushion core cover. The utility model is characterized in that the back cushion core cover is made of flexible expanded plastic material and the fillings are made of chopped flexible material. Comparing with the conventional art, the utility model has the advantages that the utility model utilizes the back cushion core cover of polyurethane matters and fillings of granular polyurethane, and the intrinsic property of the polyurethane greatly improves air permeability of the back cushion and keeps finite elasticity, therefore, when sleeping for a long time, the user is not easy to fatigue, and also enhances comfort. Moreover, the fillings of granular polyurethane are made of leftovers and crumbs from factory manufacture, thereby greatly reducing cost.
Description
Technical field
The utility model relates to a kind of bedding, relates in particular to a kind of back cushion.
Background technology
Time of 1/3rd of people is spent in sleep, and the good ring of sleep quality directly has influence on people's the state of mind and productive life.Existing back cushion generally includes back cushion and is wrapped in the outer pillow sham of this back cushion core.A kind of back cushion or pillow are to adopt polyurethane material to make, utilize foamed forming process to make all-in-one-piece back cushion or pillow, this back cushion or pillow adopt the moulding that meets the human physiological structure, being fit to very much people uses, the patent No. is that 200410071403.1 Chinese patent " pillow and manufacture method thereof " is also reported for this reason, this pillow, the core layer of the polyurethane foam system of hardness is high and low resilience and the top layer that coats the polyurethane foam system lower than this core layer hardness of this core layer form, and has first protuberance and low second protuberance than first protuberance, wherein: this core layer is increased in its width both ends side, cover the above-mentioned top layer attenuate of this part simultaneously, therefore, provide a kind of on this pillow in bed, no matter lie on the back or lie on one's side and all do not influence sleeping peacefully property, can improve the pillow of disadvantage that WA produces the sense of DOMS really, but, the pillow of this kind global formation or back cushion, working condition is relatively harsher, in foaming process, influenced by raw material and operating condition, can produce certain waste material, it is undesirable particularly to foam, pillow of making or back cushion are good inadequately as resilience on some quality index, can't normally use, as the waste product substandard products, perhaps, in the molding surface process, need cut away part material or the like, also can produce a large amount of obsolete materials, if do not add utilization, both increased production cost, and, abandon or just burn and pollute the environment, so this technology and product also need to do further improvement, preferably can be in conjunction with the supplement production method of twice laid, these part substandard products are used once more, and reduce cost; Another kind of pillow or back cushion are made up of sleeping pillow and the filler that is loaded in this sleeping pillow.As the patent No. is " the foaming plastic bead pillow " of 94206977.3 Chinese patents, and this kind pillow comprises the lining cover, it is characterized in that inserting therein foaming plastic bead, its particle diameter is 0.5-10mm, and the selection of filler has very big influence to the comfort level of sleep, and present pillowcase often adopts general cloth individual layer to make, though pillow is simple in structure like this, but elasticity is bad, and comfortableness is not strong, and is of long duration, the people is tired easily, feels uncomfortable; Moreover the height of pillow is generally all definite, and the height that change pillow is changed pillow with regard to needs, and versatility is poor, and the special mould of bead moulding needs, makes its production technology decline.
Summary of the invention
Technical problem to be solved in the utility model be provide an elasticity at the above-mentioned state of the art and gas permeability is good, simple and reasonable, to the foamed plastic manufacturing condition rely on to reduce, production technology is good back cushion.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: a kind of back cushion, it comprises the back cushion core and is wrapped in the outer pillow sham of this back cushion core, described back cushion core is made up of back cushion core retainer plate and the filler that is loaded in this back cushion core retainer plate, it is characterized in that described back cushion core retainer plate is to adopt to have the cover that flexible foamed plastic sheet is formed by connecting, described filler adopts the flexible foamed plastic material of chunky shape.
As improvement, described flexible foamed plastic sheet is the polyurethane sheet that adopts slow resilience, accordingly, filler also adopts the polyurethane of chunky shape, and flexible foamed plastic sheet is divided into slice and following sheet, last slice and following sheet be coated with cloth and following cloth respectively, by connecting line will go up cloth, last slice, down sew and couple together in the marginal portion of sheet and following cloth, makes to couple together more firmly between the sheet material, be not easy to tear, improve firmness, and avoided using the bonding connection of glue.
As improvement, described flexible foamed plastic sheet is to adopt the sponge sheet material, accordingly, filler also adopts the sponge of chunky shape, and flexible foamed plastic sheet is divided into slice and following sheet, last slice and following sheet be coated with cloth and following cloth respectively, by connecting line will go up cloth, last slice, down sew and couple together in the marginal portion of sheet and following cloth, makes to couple together more firmly between the sheet material, be not easy to tear, improve firmness, and avoided using the bonding connection of glue.
Improve, described pillow sham inwall is sewed with interlayer with nonwoven, is filled with fine hair in the interlayer again, and fine hair is selected goose feather or drake feather or staple fibre fine hair for use, makes the more comfortable softness of back cushion, and is ventilative and kept certain elasticity of back cushion core.
Further improve, position, described pillow sham neighboring is provided with the keying device that is used to pick and place the back cushion core.
Preferably, described flexible foamed plastic sheet thickness is in the 0.5-3 cm range; Described fragment diameter can keep better elastic and gas permeability like this in the 0.5-3 cm range, and comfortableness is better.
At last, described keying device adopts slide fastener, button or male and female hasp.
Compared with prior art, advantage of the present utility model is: adopt polyurethane or the back cushion core retainer plate of sponge material and the filler of graininess polyurethane or sponge, because the intrinsic characteristic of material, make the gas permeability of back cushion improve greatly, and can keep certain elasticity, has good rebound performance, be not easy fatigue by people of a specified duration, therefore comfort level also increases, moreover, the filler of polyurethane or sponge can be leftover bits and pieces or the chip in the production process of factory, and cost reduces greatly, need not that moulding has tighter process condition to foamed plastic as monoblock type back cushion core, be exactly that the foamed plastic moulding is undesirable, also can use, not obvious to back cushion core quality influence, thus the effect that acquisition is turned waste into wealth; The fine hair interlayer further gas permeability and the flexibility of having improved be set, feel is better; The design of mechanism for opening/closing on the position, pillow sham neighboring makes the adjusting of back cushion height to realize by what back cushion core of filler, has enlarged the versatility of back cushion; Back cushion overall structure advantages of simple, good manufacturability is convenient to produce, and is with low cost, relatively is fit to the supplement production method that combines with the production of monoblock type back cushion core.
