Abstract
The utility model discloses a back cushion comprising a back cushion body and an outer sleeve, wherein the back cushion body is a triangular prism; the bottom surface of the triangular prism of the back cushion body is in a triangle shape; the back cushion body is divided into a first back cushion part and a second back cushion by a plane vertical to the bottom surface of the triangular prism and penetrating through the perpendicular bisector of one edge of the triangle; the surfaces of the first back cushion part and the second back cushion are wrapped by the outer sleeve, and the foldable movable connection is implemented between the first back cushion part and the second back cushion by taking a connecting part of the outer sleeve as a rotating shaft. Since the back cushion provided by the utility model has a folding function, the length of the folded back cushion is decreased and the occupation area of the folded back cushion is decreased to relatively beneficially stored and transported, and the folded back cushion body is square, and is quite beautiful.
Description
Technical field
The utility model relates to daily medical treatment and nursing articles for use field, relates in particular to a kind of back cushion.
Background technology

Therefore, traditional wedge shape leans to pad and usually to user, brings inconvenience.
Utility model content
The purpose of this utility model is to provide a kind of back cushion, to address the above problem.
In order to achieve the above object, the technical solution of the utility model is achieved in that
A back cushion, comprises back cushion body and overcoat; Described back cushion body is tri-prismoid;
The tri-prismoid bottom surface of described back cushion body is triangle; Described back cushion body is divided into the first back cushion portion and the second back cushion portion by vertical described tri-prismoid bottom surface and through the plane of the perpendicular bisector on a limit of described triangle;
Wrap up by described overcoat on the surface of described the first back cushion portion and the second back cushion portion, and described the first back cushion portion and described the second back cushion portion take overcoat junction as turning cylinder, forms folding flexible connection.
Compared with prior art, the advantage of the utility model embodiment is:
A kind of back cushion that the utility model provides, analyzes above-mentioned bolster apparatus known: back cushion body is tri-prismoid; And the tri-prismoid bottom surface of described back cushion body is triangle; Described back cushion body is divided into the first back cushion portion (than the less tri-prismoid of former tri-prismoid back cushion body) and the second back cushion portion by vertical described tri-prismoid bottom surface and through the plane of perpendicular bisector on a leg-of-mutton limit;
Overcoat has wrapped up above-mentioned two back cushion portions, and connect two back cushion portions by overcoat, the collapsible connection of two back cushion portions can be realized as turning cylinder in this overcoat junction, when such the first back cushion portion turns to certain angle along turning cylinder, tapered plane of the first back cushion portion and the laminating of the tapered plane of the second back cushion portion, the special shape itself having due to back cushion body like this, causes the back cushion length after folding to diminish, and be folded into a global shape, be so more conducive to store and transport.And the back cushion body floor space after folding diminished, be convenient to deposit and transport.
When user does not need to use, back cushion can be folded up, very easy to use.

The specific embodiment
Below by specific embodiment, also by reference to the accompanying drawings the utility model is described in further detail.
Embodiment mono-
Referring to Fig. 1, Fig. 2 and Fig. 3, a kind of back cushion that the utility model embodiment mono-provides, comprises back cushion body 1 and overcoat 2; Described back cushion body 1 is tri-prismoid;
The tri-prismoid bottom surface 10 of described back cushion body 1 is triangle; Described back cushion body 1 is divided into the first back cushion portion 20 and the second back cushion portion 30 by vertical described tri-prismoid bottom surface 10 and through the plane (Fig. 2 midplane X) of the perpendicular bisector on a described leg-of-mutton limit;
The surface of described the first back cushion portion 20 and the second back cushion portion 30 is by described overcoat 2 parcels, and described the first back cushion portion 20 take overcoat junction as turning cylinder with described the second back cushion portion 30, forms folding flexible connection;
In the utility model embodiment mono-, back cushion body is tri-prismoid; And the tri-prismoid bottom surface of described back cushion body is triangle; Described back cushion body is divided into the first back cushion portion (than the less tri-prismoid of former tri-prismoid back cushion body) and the second back cushion portion by vertical described tri-prismoid bottom surface and through the plane of perpendicular bisector on a leg-of-mutton limit;
Overcoat has wrapped up above-mentioned two back cushion portions, and connect two back cushion portions by overcoat, the collapsible connection of two back cushion portions can be realized as turning cylinder in this overcoat junction, when such the first back cushion portion turns to certain angle along turning cylinder, tapered plane of the first back cushion portion and the laminating of the tapered plane of the second back cushion portion, the special shape itself having due to back cushion body like this, causes the back cushion length after folding to diminish, and be folded into a global shape, be so more conducive to store and transport.And the back cushion body floor space after folding diminished, be convenient to deposit and transport.
Preferably, the tri-prismoid bottom surface of described back cushion body is right angled triangle;
The tapered plane intersection of described plane (being plane X) and described back cushion body is coaxial with described turning cylinder.
Wherein, the tri-prismoid that bottom surface is right angled triangle as a kind of preferably can embodiment.In this preferred scheme, the tri-prismoid bottom surface of back cushion body is right angled triangle, so, described back cushion body can be divided into the first back cushion portion and the second back cushion portion by vertical described tri-prismoid bottom surface and for example, through the plane of the upper perpendicular bisector in a limit of described right angled triangle (: be preferably right-angle side), equally, overcoat has wrapped up above-mentioned two back cushion portions, and connect two back cushion portions by overcoat, the collapsible connection of two back cushion portions can be realized as turning cylinder in this overcoat junction, obviously when turning cylinder and (the tapered plane intersection of described plane and described back cushion body) are coaxial, can prove that this junction is positioned on the center line of back cushion body tapered plane, when such the first back cushion portion turns to certain angle along turning cylinder, tapered plane of the first back cushion portion and the laminating of the tapered plane of the second back cushion portion, the special shape itself having due to back cushion body like this, cause the back cushion length after folding to diminish, and be folded into a rectangular shape, so more be conducive to store and transport, and having the shape of a real square very saving of the back cushion body after folding taken up an area space and better appearance (referring to Fig. 4).
