Mattress edge protection spring and mattress

Abstract

The invention discloses a mattress edge protection spring and a mattress. The edge protection spring is formed by integrally winding a steel wire and comprises a top edge, a bottom edge and an elastic connecting part connected between the top edge and the bottom edge, and the middle of the elastic connecting part is not located on the plane where the top edge and the bottom edge are located and deviates to one side. The elastic connecting part in the middle of the edge protecting spring is not located on the plane where the top edge and the bottom edge are located and deviates to one side, so that when the edge protecting spring is installed on the side wall of the mattress, the edge protecting spring is placed in the mode that the elastic connecting part deviates to the inner side of the mattress, and then the top edge and the bottom edge of the edge protecting spring are fixed to the top and the bottom of the side wall of a spring layer of the mattress respectively. A plurality of edge protection springs are arranged on the four side walls of the mattress according to the mode. When a person sits on the edge of the mattress, the top edge of the edge protecting spring compresses the elastic connecting part downwards due to extrusion, and the elastic connecting part deviates to the inner side of the mattress, so that even if the edge protecting spring is extruded to deform and protrude, the edge protecting spring only protrudes towards the inner side of the mattress and does not bulge towards the outer side of the mattress.

Description

technical field [0001] The invention relates to the technical field of spring mattresses, in particular to a mattress side spring and a mattress. Background technique [0002] The spring layer of existing spring mattress usually adopts spring disks to form together. When the user lies on the mattress, the spring mattress evenly supports every part of the body, keeps the spine naturally straight, fully relaxes the muscles, and sleeps better. In order to ensure comfort, the hardness of the springs in the spring mattress is relatively soft, but when this spring mattress is pressed down by a large gravity, it is easy to deform and collapse, and the service life is short. For this reason, a kind of spring mattress has appeared on the market, as patent document CN210095228U, and this patent document discloses a kind of spring mattress, and its side wall is provided with the mattress supporting frame with elastic force, and mattress supporting frame hardness is higher than mattres...

Problems solved by technology

However, the top edge, the elastic part and the bottom edge of the mattress supporting frame disclosed in this patent document are all on a plane, if the user often sits near the edge of the mattress, the middle part of the mattress supporting frame is often squeezed It is easy to deform and protrude outward, causing the outer side of the mattress to bulge, affecting the appearance
