Abstract

The utility model relates to a double-layer spring bed cushion, comprising a spring framework 1 and a covering layer 2. The covering layer 2 is covered outside the spring framework 1; the spring framework 1 comprises a surrounding-frame steel wire 3 forming the surrounding-frame and a spring layer 4 circled by the surrounding-frame steel wire 3; the spring layer 4 comprises a plurality of parallel-arranged spring groups 5 and serial-strip steel wire 6; the serial-strip steel wire 6 successively connects in series the end sides of each neighboring spring of the neighboring spring groups. The utility model is characterized in that the spring layer 4 has the upper and the lower layers, the spring on the upper spring layer and the spring on the lower spring layer are overlapped vertically, and the lower part of the spring on the upper spring layer and the upper part of the spring on the lower spring layer are twinedly connected by steel wires. The utility model has excellent elasticity and the user can use in a long term without deformation and sinking.

Description

The double-layer spring mattress

Technical field:

The utility model relates to a kind of sping mattress.Particularly relate to a kind of double-layer spring mattress.Belong to the bedding technical field.

Background technology:

Existing sping mattress is made of spring skeleton and clad usually.The spring skeleton is sealed by clad.And existing spring skeleton mainly constitutes by enclosing the frame steel wire and being enclosed the spring layer that frame steel wire circle encloses by this, encloses the frame that encloses that the frame steel wire has formed a sealing.The shape of enclosing frame is generally rectangle.Above-mentioned spring layer generally is made of the multirow groups of springs of laterally arranging side by side, and each groups of springs is made of a plurality of springs, on the same group between each spring with similar connector serial connections such as string bars, each spring of periphery with enclose frame and be connected with going here and there similar connector such as bar.In existing sping mattress, set spring is one deck, and elasticity is relatively poor, spring skeleton easy deformation, subsides, and mattress is short service life, causes easily after the user uses for a long time and has a pain in the back.

Summary of the invention:

The purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of elasticity better, the not yielding double-layer spring mattress that subsides of the long-term use of user.

The purpose of this utility model is achieved in that a kind of double-layer spring mattress, comprise spring skeleton and clad, clad is coated on outside the spring skeleton, the spring skeleton comprises constituting and encloses enclosing the frame steel wire and being enclosed the spring layer that frame steel wire circle encloses by this of frame, spring layer comprises the multirow groups of springs and the string bar steel wire of arranging side by side, string bar steel wire twines serial connection with each adjacent springs end spring coil of adjacent springs group successively, on being characterized in that spring layer has, following two layers, the spring of the spring of upper spring layer and lower spring layer is overlapped vertical, and the spring top of the spring bottom of upper spring layer and lower spring layer twines with steel wire and connects.

Compare with existing like product, in mattress of the present utility model, the height of every spring is 1/2nd of an existing similar mattress spring, because the spring height obviously reduces, with respect to same material, with the taller springs in waist footpath, its bearing capacity in the elastic deformation scope obviously improves, and elastic strength increases, spring is more not fragile, longer service life.And for mattress generally, its deformation on a certain position vertical can be considered the vertical deformation sum of two springs of the state in an overlapping at this position, thereby guarantees that mattress has enough elasticity.Avoided because of subsiding that the deformation of mattress local plastic occurs.Prolonged the service life of mattress.

Description of drawings:

Fig. 1 is a risers structure cut-away view of the present utility model.

Fig. 2 is the planar structure schematic diagram of spring skeleton of the present utility model.

The specific embodiment:

As Fig. 1～2, the utility model is a kind of double-layer spring mattress, is made up of double-layer spring skeleton 1 and clad 2.Clad is coated on outside the spring skeleton 1.Spring skeleton 1 comprises constituting and encloses frame and enclose frame steel wire 3 and enclosed the spring layer 4 that frame steel wire 3 circles enclose by this and form.Spring layer 4 is made up of upper and lower spring layer 7,8.Upper and lower spring layer 7,8 is formed by similar connector 6 such as a plurality of groups of springs 5 of arranging side by side and spiral string bar.String bar 6 twines serial connection with each adjacent springs end spring coil of adjacent springs group successively, to form the reinforced catapult spring assembly.The upper/lower terminal end spring coil of spring is buckled on the frame that encloses frame steel wire 8.Each spring is to be made by single continuous wire.The spring of the spring of upper spring layer 7 and lower spring layer 8 is overlapped vertical, and the spring top of spring 7 bottoms of upper spring layer and lower spring layer 8 twines with steel wire and connects.
