Technical Field

The invention relates to the technical field of spring mattresses, in particular to a mattress edge protection spring and a mattress.

Background

The spring layers of the prior spring mattress are usually formed by spring coils which are knotted together. When a user lies on the mattress, the spring mattress uniformly supports each part of the body, keeps the spine naturally straight, enables muscles to be fully relaxed and has a good sleeping effect. In order to ensure comfort, the spring hardness in the spring mattress is soft, but when the spring mattress is pressed by larger gravity, the spring mattress is easy to deform and collapse, and the service life is shorter. For this reason, a spring mattress is commercially available, for example, patent document CN210095228U, which discloses a spring mattress, the side wall of which is provided with a mattress support frame with elastic force, the hardness of the mattress support frame is harder than that of the spring in the mattress, so that when the spring mattress is pressed by large gravity, the support springs on the side wall of the mattress can play a role of supporting, the pressure on the spring in the middle of the mattress is reduced, the spring mattress is prevented from collapsing, and the service life of the spring mattress is prolonged. However, the top edge, the elastic part and the bottom edge of the mattress supporting frame of the spring mattress disclosed in the patent document are all on a plane, if a user frequently sits at a position close to the edge of the mattress, the middle part of the mattress supporting frame is frequently extruded and easily deformed and protrudes outwards, so that the outer side of the mattress is bulged, and the appearance is affected.

Disclosure of Invention

The invention aims to provide a mattress edge-protecting spring and a mattress provided with the same, wherein the edge-protecting spring can avoid the bulge of the outer side of the mattress.

In order to solve the technical problem, the mattress edge-protecting spring comprises a top edge, a bottom edge and an elastic connecting part connected between the top edge and the bottom edge, wherein the middle part of the elastic connecting part is not positioned on the plane of the top edge and the bottom edge but is deviated to one side.

Optionally, the elastic connection portion includes a left elastic connection portion and a right elastic connection portion, the left elastic connection portion connects the left end of the top edge and the left end of the bottom edge, and the right elastic connection portion connects the right end of the top edge and the right end of the bottom edge.

Optionally, the middle of the left elastic connecting portion is arched to the right, and/or the middle of the right elastic connecting portion is arched to the left.

Optionally, the elastic connecting part is wound around the arch at the middle part for one or more turns.

Optionally, the steel wire is integrally wound to form the steel wire.

The utility model provides a mattress, includes spring layer and the bed of cloth of cladding at spring layer surface, spring layer lateral wall install as above mattress safe edge spring, the inboard of the elastic connection portion's of safe edge spring middle part deviation spring layer.

The elastic connecting part in the middle of the edge protection spring is not positioned on the plane of the top edge and the bottom edge and is deviated to one side, so that when the edge protection spring is installed on the side wall of the mattress, the edge protection spring is placed to be deviated to the inner side of the mattress, then the top edge and the bottom edge of the edge protection spring are respectively fixed at the top and the bottom of the side wall of the spring layer of the mattress, and a plurality of edge protection springs are installed on the four side walls of the mattress according to the mode. When the people sat at the mattress edge, the topside of safe edge spring compressed elasticity connecting portion downwards because of receiving the extrusion, because elasticity connecting portion are inboard towards the mattress, even the safe edge spring receives the extrusion and deformation protrusion, also can only bulge towards the mattress inboard, can not bulge toward the mattress outside.

Detailed Description

The invention is described in further detail below with reference to specific embodiments.

The mattress shown in fig. 4 comprises a spring layer 20, and a plurality of border springs 10 shown in fig. 1 are mounted on the peripheral side walls of the spring layer 20. The edge spring 10 is formed by integrally winding a steel wire. The top edge 1 and the bottom edge 2 of the edge-protecting spring 10 are respectively fixed on the top and the bottom of the side wall of the spring layer 20 (see fig. 4). As shown in fig. 1, an elastic connection portion 3 is connected between the top edge 1 and the bottom edge 2 of the edge protection spring 10, and the elastic connection portion 3 includes a left elastic connection portion 31 and a right elastic connection portion 32. The left elastic connecting portion 31 connects the left end of the top edge 1 and the left end of the bottom edge 2, and the middle portion of the left elastic connecting portion 31 is arched rightward. The right elastic connecting part 32 connects the right end of the top edge 1 and the right end of the bottom edge 2, and the middle part of the right elastic connecting part 32 is arched leftwards. So, there is the contained angle between the first half section and the second half section of left and right elastic connecting portion 31, 32 for there is deformation resilience force between first half section and the second half section. When topside 1 compressed left and right elastic connecting portion 31, 32 downwards because of receiving the extrusion, first section receives the extrusion and down the half is close to for contained angle between the two reduces, when topside 1 no longer receives the extrusion, so the first section of left and right elastic connecting portion 31, 32 no longer receives the extrusion and so keeps away from second section and return to initial position, makes the contained angle between first section and the second section resume to initial angle. The arch crown 33 in the middle of the left and right elastic connecting parts 31 and 32 is surrounded by two circles, so that the deformation resilience force between the upper half section and the lower half section of the left and right elastic connecting parts 31 and 32 can be increased. As shown in fig. 2 or 3, the middle portions of the left and right elastic connecting portions 31, 32 are not located on the plane of both the top edge 1 and the bottom edge 2 but are offset to one side. In the mounted state as shown in fig. 4, the middle portions of the left and right elastic connecting portions 31, 32 are biased toward the inside of the spring layer 20. After the edge springs 10 are installed, the outer surface of the spring layer 20 is covered with a cloth layer (not shown), so that a complete spring mattress is assembled. When a person sits on the edge of the spring mattress, the top edge 1 of the edge protection spring 10 is pressed to compress the elastic connecting part 3 downwards, and the elastic connecting part 3 is deviated to the inner side of the mattress, so that even if the edge protection spring 10 is pressed to deform and protrude, the edge protection spring only protrudes towards the inner side of the mattress and cannot bulge towards the outer side of the mattress.

The above description is only the embodiments of the present invention, and the scope of protection is not limited thereto. The insubstantial changes or substitutions will now be made by those skilled in the art based on the teachings of the present invention, which fall within the scope of the claims.
