Abstract
Disclosed is a support bracket for a spring cushion of a sofa, which comprises a frame (10) and a plurality of pullback springs (20) evenly and fixedly distributed on the frame (10); a plurality of pullback springs (20) are windingly extended along the radial direction of a sitting surface in an S or a Z shape; and the support bracket further includes at least one transverse connecting rod (30) crossed and connected the pullback springs (20); the side surface of the pullback springs (20) presents an upper-bent arc shape; and the pullback springs (20) form an arc-shaped sitting surface (19) with comfort feeling. Compared with prior art, the support bracket for a spring cushion of a sofa has the advantages that the when the sofa bears uneven force, the sofa can not easily reach the compression limit at a stresses point, and people can not has the feeling of sudden sinkage when sitting on.
Description
Technical field
The utility model relates to a kind of support bracket of Sofa cushion, relates in particular to a kind of support bracket of spring sofa cushion.
Background technology
Existing sofa generally adopts the spring of tubulose, waits the comfort level of regulating sofa by the soft durometer that changes sleeve.All be independently between each sleeve, put stressed excessively, be easy to just arrive the compression limit of spring as the spring at that place that the people sat down when sofa.
The utility model content
The technical problems to be solved in the utility model is to provide a kind of support bracket of spring sofa cushion, when sofa in discontinuity the time, also is not easy to reach compression limit at the stress point place, does not just have a sensation that sits on the end when people takes.
In order to solve the problems of the technologies described above, the utility model designs a kind of support bracket of spring sofa cushion, comprise frame and evenly be installed in many extension springs of described frame, described many extension springs are vertically returned Qu Yanshen by S shape or z shape along what take face, comprise that also at least one crosses over and link the horizontal connecting rod of described many extension springs, it is slightly arc to what arch up that the side of described extension spring is, and arc arcuation with comfort of described many extension springs structure is taken face.Like this, when described extension spring one place begins stressed the time, extension spring herein begins deformation to be elongated, and extension spring forms arcuate arc and descends, but when this arcuate arc is approaching when taking face, this extension spring still has the leeway that can further be elongated.Therefore,, also be not easy to reach compression limit, just do not have a sensation that sits on the end when people takes at the stress point place when sofa the time in discontinuity.
As an embodiment of the present utility model, the front of described frame and back are matched respectively front hook and the aft hook that equates with described extension spring quantity are set, the front end of described extension spring is hooked in described front hook by drag hook, and the rear end of described extension spring is hooked in described aft hook.Described drag hook can serve as that axle rotates with described front hook.Like this, the binding of described drag hook and extension spring is movable, the movable up-downgoing space that increases extension spring, thus the elasticity of extension spring is fully used, strengthen the comfort level of sofa.
Front end the 1st joint S shape of described extension spring or z shape are returned tune to be had to become with described frame face near the turning up of right angle, and makes the radius of curvature of described extension spring front end less than the radius of curvature of rear end.
Associative perception when taking in order further to strengthen sofa, when preventing that local pressure is excessive, the extension spring deformation at this place is excessive, and laterally connecting rod has three, is parallel to described front and back and is provided with, wherein the place that turns up that is connected to every extension spring.Can also further limit described extension spring like this and laterally or vertically produce deformation, and make stressed more even.
Fixedly connected in order to guarantee more reliable and described extension spring, fixedly connected by the casing pressure steel loop between described horizontal connecting rod and the described extension spring, adopt the outer diameter that is enclosed with brown paper greater than 2 millimeters steel wire.
As the utility model embodiment more specifically, the distance between the described horizontal connecting rod is equal substantially.
The quantity of described extension spring is four, and described extension spring adopts diameter greater than 3 millimeters steel wire.
The length of described front and back is 60 to 70 centimetres, and the distance between described front and the back is 40 to 55 centimetres; The arc height that described arc arcuation is taken face is at least 5 centimetres.
Compared with prior art, the advantage of the support bracket of spring sofa cushion of the present utility model is that this Sofa mattress also is not easy to reach compression limit at the stress point place in discontinuity, does not just have a sensation that sits on the end when people takes.
Description of drawings
Fig. 1 is the plan structure schematic diagram of a kind of embodiment of support bracket of spring sofa cushion of the present utility model;
Fig. 2 is the side-looking structural representation of a kind of embodiment of support bracket of spring sofa cushion of the present utility model.
The specific embodiment
Be described in further detail below in conjunction with the most preferred embodiment shown in the accompanying drawing.
As depicted in figs. 1 and 2, the support bracket of spring sofa cushion of the present utility model comprises: comprise two relative fronts 11 and back 12 four edges frames 10, four by return Qu Yanshen the extension spring 20 that forms of wire, and three horizontal connecting rods 30 that are parallel to described front 11 and back 12 settings, described horizontal connecting rod 30 is fixedlyed connected with the described extension spring 20 of each bar successively.Arc arcuation with comfort of described many extension springs 20 structures is taken face 19.
As shown in Figure 1, the front 11 of described frame 10 and back 12 are matched respectively and are provided with front hook 41 and aft hook 42.The front end of described extension spring 20 is hooked in described front hook 41 by drag hook 50, and the rear end of described extension spring 20 is hooked in described aft hook 42.As shown in Figure 2, the front end of described extension spring 20 the 1st joint S shape or Z-shaped time tune have to become with 10 on described frame near the turning up of right angle, and have a horizontal connecting rod 30 to be connected to the place that turns up of every extension spring 20.Like this, the radius of curvature of described extension spring 20 front ends is less than the radius of curvature of rear end.
Fixedly connected by the casing pressure steel loop between described horizontal connecting rod 30 and the described extension spring 20, adopt the outer diameter that is enclosed with brown paper greater than 2 millimeters steel wire.The quantity of described extension spring 20 is four, and described extension spring 20 adopts diameters greater than 3 millimeters steel wire.
As Fig. 1, the distance between the described horizontal connecting rod 30 is equal substantially.The length of described front 11 and back 12 is 60 to 70 centimetres, and the distance between described front 11 and the back 12 is 40 to 55 centimetres; As Fig. 2, the arc height that described arc arcuation is taken face 19 is at least 5 centimetres.
