CN2653217Y - Independent through-net spring mattress - Google Patents

Abstract

The utility model relates to an independent type through spring mattress saddle, which is characterized in that a revolving spring is divided into a beginning end winding, an end winding and a through winding, the trough winding is arranged between the beginning end winding and the end winding, the trough winding of the trough winding is bigger than the trough windings of the beginning end winding and the end winding, crossunder lines crosses under the trough winding of each revolving spring, making the utility model to be a reticular saddle with only one layer of through layer. The utility model has a simple and rational structure. When people are sitting on the saddle, the seated springs will be compressed, the effect that the other springs continue the lower concave is less, achieving the effect of the absolute spring pad net, and the utility model has the advantages of convenient weave and assembly, low cost, suitable for the spring saddle such as the mattress and the sofa cushion.

Description

Independent is worn the net spring mattress saddle

Technical field

The utility model relates to a kind of cushion, and particularly a kind of independent is worn the net spring mattress saddle.

Background technique

It is bigger that existing spirality is worn the circle footpath of the top pitch of the laps of net spring (as shown in Figure 1 and Figure 2) and terminal pitch of the laps, when piecing together netted pad with their cross-under of cross-under bundle of lines, needs a minute upper and lower two-layer cross-under.Like this, when people's seat during,, can not reach the effect of independent spring pad net, and cost is also higher because the interconnect function of upper and lower two-layer cross-under line can make full wafer wear the net spring to lower recess in pad.

Summary of the invention

It is a kind of simple in structure that the purpose of this utility model is to provide, and has only one deck pnet erforating layer, wears the net amalgamation conveniently, and cost is lower, and the independent that can reach independent spring pad net effect is worn the net spring mattress saddle.

The purpose of this utility model can reach by following measure: a kind of independent is worn the net spring mattress saddle, it is characterized in that: revolve the shape spring body and be divided into top pitch of the laps, terminal pitch of the laps, wear the net pitch of the laps, wear the net pitch of the laps between top pitch of the laps and terminal pitch of the laps, its circle footpath is greater than top pitch of the laps and terminal pitch of the laps, the cross-under line is connected to wearing on the net pitch of the laps of each spiral spring body, makes its formation have only the netted pad of one deck pnet erforating layer.

The purpose of this utility model can also reach by following measure: wear the longitudinal axis of the plane at net pitch of the laps place perpendicular to the helical spring body.

The utility model has following advantage compared to existing technology: simple and reasonable, have only one deck pnet erforating layer, people's seat when pad, by seat several springs can compress, the recessed influence of other spring interlock is less, reaches independent spring pad net effect.And it is convenient to wear the net amalgamation, and cost is lower, is applicable to spring pads such as mattress, sofa cushion.

Structural representation when Fig. 7, Fig. 8 adopt another kind of shape for helical spring.

Embodiment

The utility model is described in further detail below in conjunction with accompanying drawing (embodiment):

With reference to Fig. 3～Fig. 6, spiral spring body 1 is divided into top pitch of the laps 2, terminal pitch of the laps 3, wears net pitch of the laps 4 three parts.Wear net pitch of the laps 4 between top pitch of the laps 2 and terminal pitch of the laps 3, its circle footpath is bigger than top pitch of the laps 2 and terminal pitch of the laps 3.Wear net pitch of the laps 4 and become a plane basically, perpendicular to the longitudinal axis of helical spring body 1.In the time will piecing together netted pad, can be connected to wearing on the net pitch of the laps 4 of each spiral spring body 1 wearing netting twine 5, make it form netted pad.Owing to only form one deck pnet erforating layer, when people's seat is on pad, by seat several springs be compressed, the recessed influence of other spring interlock is less, reaches the effect of independent spring pad net.

Wear gauze pad circle 4 and also can be made into, be more conducive to 5 cross-under of cross-under line as Fig. 7, shape shown in Figure 8.

Claims (2)

1, a kind of independent is worn the net spring mattress saddle, it is characterized in that: revolve shape spring body (1) and be divided into top pitch of the laps (2), terminal pitch of the laps (3), wear net pitch of the laps (4), wearing net pitch of the laps (4) is positioned between top pitch of the laps (2) and the terminal pitch of the laps (3), its circle footpath is greater than top pitch of the laps (2) and terminal pitch of the laps (3), cross-under line (5) is connected to wearing on the net pitch of the laps (4) of each spiral spring body (1), makes its formation have only the netted pad of one deck pnet erforating layer.

2, cushion according to claim 1 is characterized in that: wear the longitudinal axis of the plane at net pitch of the laps (4) place perpendicular to helical spring body (1).
