Abstract

The utility model discloses a Simmons mattress which is composed of a bed frame, cloth, and a mattress layer, wherein, the cloth and the mattress layer are coated at the outside of the bed frame, and the bed frame is composed of a spring assembly. The utility model is characterized in that a torsional spring with two spring rings is adopted by a lifting spring, arms corresponding to the two spring rings are formed as a whole which forms a n shape, the two arms form an axial symmetry along the two spring rings, and an included angle of the two arms is less than 180 DEG. The structure of the lifting spring of the utility model has the advantages that the arms are uniformly stressed and are not easy to be deformed, and the noise of 'cheep' 'cheep' caused by the friction of the torsional springs can be avoided.

Description

Padding for spring bed

The utility model relates to a kind of sping mattress that rigid frame is arranged, and particularly relates to the padding for spring bed that a kind of mattress has used lifting spring all around.

The elastic parts of padding for spring bed inside mainly is made up of upright spring, helical spring and lifting spring and all frames.Upright one by one spring is connected by helical spring to be combined, and forms the main body of spring bedstead, and the circumferentially-spaced of upright spring main body is provided with lifting spring, and they and all frames are intertwined and connected with helical spring, close as a whole with upright spring body junction.Lifting spring generally adopts torsion spring, and its effect mainly is to guarantee that mattress perimeter forms the elastic force of ad hoc fashion, so that the human body seat has comfortable sensation in the edge of mattress.But this single arm type torsion spring (see figure 1) cause stress point asymmetric, inhomogeneous, and elasticity is little, yielding because support arm is asymmetric, makes the human body seat uncomfortable thereon; In addition, this mattress thereon the time, can produce the sound of " creaking ", " creaking " at people's seat, and this mainly is that the torsion spring unbalance stress of this shape produces due to the friction.

Goal of the invention of the present utility model is to provide a kind of can overcome the defective that prior art exists, stressed even, the comfortable padding for spring bed of mattress perimeter.

Goal of the invention of the present utility model is achieved in that lifting spring does not adopt the single arm type torsion spring, but adopts a kind of torsion spring of new-type structure on the basis of existing padding for spring bed.The structure of this kind torsion spring is: torsion spring has two turns, and two corresponding support arms of turn are one, are " Jiong " shape.Two support arms are along the coaxial symmetry of two turns, and two planes that form are the angle less than 180 °.

The torsion spring of this structure, because support arm is symmetrical, and support arm two ends all produce torsional stress.Therefore this torsion spring is installed in the periphery of mattress as the lifting spring, stressed evenly, not yielding, and not because of fricative " creaking ", " creaking ".

Below with reference to accompanying drawing embodiment of the present utility model is done further detailed description.

Fig. 1 is the structural representation of existing torsion spring.

Fig. 2 is the partial sectional view of the utility model embodiment;

Fig. 3 is Figure 1A-A cutaway view;

Fig. 4 is the structural representation of lifting spring.

Referring to Fig. 2, Fig. 3.The bottom of padding for spring bed tissue layer lining (1) is a bed course, they are made up of spongy layer (2), cotton carpet veneer (3) and numb carpet veneer (4), be coated on spring bedstead wherein for the spring assembly formation, the main body of spring bedstead is by founding spring (9) one by one, combining through helical spring (8) connection, the circumferentially-spaced of upright spring main body is provided with lifting spring (6), and lifting spring (6) is a torsion spring, and it has two turns (10), the corresponding support arms of two upper spring circles (1) are one, are " Jiong "

Shape, two support arms are along the nominal symmetry of two upper spring circles, and two planes that form are the angle less than 180 °, a support arm (11) of torsion spring is wrapped on the end great circle of all frames (7) and upright spring (9) by helical spring (8), another support arm is wrapped on the great circle of the other end of all frames (7) and upright spring (9) by helical spring (8) equally, and whole sping mattress is enclosed within the plastic wire (5).

Claims

1, a kind of padding for spring bed, the bedstead that it is made of spring assembly and be coated on outer field tissue layer and bed course is formed, the main body of spring bedstead is to combine through helical spring (8) connection by founding spring (9) one by one, the circumferentially-spaced of upright spring main body is provided with lifting spring (6), lifting spring (6) is wrapped in itself and upright spring (9) on all frames in the lump by helical spring (8), it is characterized in that: the lifting spring is a torsion spring, and it has two turns (10), two corresponding support arms of turn (11) are one, are " Jiong "

Shape, two support arms are along two coaxial symmetries of turn, and the angle of two support arms is less than 180 °.

2, padding for spring bed according to claim 1, it is characterized in that: a support arm (11) of torsion spring (6) is wrapped in by helical spring (8) on the end great circle of all frames (7) and upright spring (9), and another support arm is wrapped on the great circle of the other end of all frames (7) and upright spring (9) by helical spring (8) equally.
